'1 '0 all F/1012i. 1' it may concern:

ie it known that I, FRANZ A. FULLER, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Razor- Illades, of which the following is a'full, clear, and exact description, such as will enable others skilled in the art to which it per tains to make, construct, and use the same, reference being had to the accompanying drawings and to numerals of referen e marked thereon, forming a part of this specification.

This invention relates to certain new and useful improvements in razor blades, PI'0 vided with a longitudinal deflection serving to stifi'en and strengthen the blads, as will be herein described.

The inventitn comprises the constructing of the blade from sheet steel with a concave-l and offset portion, which will be found of importance in tempering, sharpening, honing and stropping the blade, and at the same time, presenting contacting surfacesfor the fingers in handling the blade, thereby reducing the possibilities of cutting the latter in pressing the blade into or out of position, to a minimum.

' In carryingthe invention into practice, I provide also a means for supporting the blade,

Describing the invention in detail, reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate corresponding parts throughout the several views of the drawings, and in which- Figure l represents a perspective view of ablade; and Fig. 2 represents a similar view of the means for supporting the blade, the means also being shown in operative position in dotted lines. in Fig. 1.

In the accompanyin drawings, 1 re resents a razor blade mailc of very thin s ieet steel, provided with a longitudinal cutting edge 2, and an upwardly projectin concaved portion 3 terminating into an ol fset 4, which serves to stiffen and strengthen the blade, thus rendering the same more rigid and durable in its nature.

In Fig. 1 of the drawings, I have shown my improved blade in combination with the means 7 illustrated in Fig. 2, for supporting the blade, said means being so formed and so arranged as to give to the razor blade 1 rigidity and stability, inasmuch as it is contemplated to use with the supporting means, preferably a blade of approximately the length of the so-called straight razor now in use, thereby presenting a structure in general appearance similar to said so-called straight razor. The supporting means 7 is also provided with a short concaved portion 8 extending throughout its entire length, the lower edge 9 of which is adapted to bear against the corresponding concaved portion of the razor blade 1 to support the same, said supporting means 7 being further provided with a channel-shaped portion 10 extending alongits entire length, designed to receive the offset vertical upper portion 11 of the blade 1. The supporting means 7 may be of any size and form, and if desired, may have formed integral therewith, a handle or the like.

The construction of the blade is of such a nature as to lend itself to be readily manufactured by the use of ordinary punches and dies.

Experience has demonstrated that the organization above described is a highly cilici'ent one, and while the device described is the preferred embodiment of my present in-' vention, I do not care to restrict myself to the exact details of construction, combination and arrangement herein set forth. it being obvious that minor variations thereof not involving the exercise of invention may be made by any skilled mechanic, and such departures from what is herein described and claimed not involving invention, I con sider within the scope and terms of my claim.

I claim:

The combination of a razor blade made of sheet metal provided with a substantially plane longitudinal portion, and having a single longitudinal cutting edge, said cutting edge lying approximately in an extension of said plane portion, the blade intermediate said portion and said edge havin a portion uniformly inclined from said ed ge away from the cent 'al plane of said first mentioned portion and lying entirely on one side thereof, said plane having also an off-sot portion connecting said inclined portion with said first mentioned portion, the lines of union between said offset portion and said other portion being straight lines approximately parallel to said cutting edge, and a reinforcing member for said blades comprising two plane portions arranged in This specification signed and witnessed parallel gelation and space?l agart to form (:11. this 26th day of April, 1913. groove :1 apted to receive t e rst mentione portion of said blade, said member being ex- FRANZ FULLER tended in the same general direction as said Witnesses:
